        These tests test the total time taken to execute all of Boost.Math's test
        cases for these functions. In each case the best performing library gets
        a relative score of 1, with the total execution time given in brackets. Times
        are shown for both single threaded runs and concurrent execution - the latter
        increases contension inside new/delete.
